Patent FI-90101-C (FI)
Inventor: PAV JOSEF
IPC: D21G1/00
Filed: 1988-10-17
Granted: 1993-12-27
Abstract: A process for operating a calender (1) provides that, before the uppermost roll gap is closed, the upper roll (4) is preshaped to conform to the curvature of the uppermost intermediate roll (6). To carry out this process, the upper roll (4) possesses a roll jacket (21) which is penetrated by a non-rotating shaft (22) and has primary pressure zones (27) and secondary pressure zones (28). A pressure adjustment device provides for a pressure distribution for the pressure zones (27, 28) which produces a bending deformation of the roll jacket (21) independent of external forces stemming from the adjacent roll (6). Furthermore, the upper roll (4) has a heating facility which maintains the temperature of the upper roll at a predetermined level. This allows an improvement in the glazing process accompanied by simultaneous preservation of the specific volume of the treated web.

Abstract: A metal matrix composite is formed by contacting a molten matrix alloy (18) with a permeable mass of filler material or preform (16) in the presence of an infiltrating atmosphere. Under these conditions, the molten matrix alloy (18) will spontaneously infiltrate the permeable mass of filler material of preform (16) under normal atmospheric pressures. Once a desired amount of spontaneous infiltration has been achieved, or during the spontaneous infiltration step,the matrix metal which has infiltrated the permeable mass of filler material or preform (16) is directionally solidified. This technique allows the production of spontaneously infiltrated metal matrix composites having improved microstructures and properties.

Abstract: Water-soluble crystalline material which has been comminuted in a saturated aqueous solution of the material in the presence of a water-soluble crystal-growth inhibitor having a hydrophobic portion and a hydrophilic portion in its molecular structure is mixed with a deflocculant which inhibits the interaction of the hydrophobic molecular portions whenever the comminuted solid is suspended in water. The viscosity of aqueous suspensions of comminuted solid is thereby stabilised.The invention is especially beneficial in the preparation of aqueous suspensions of finely comminuted ammonium nitrate for use in slurry blasting explosives.With crystal-growth inhibitors such as water-soluble polysaccharide derivatives, long chain aliphatic amines, polyacrylic acids, sulphonated nuclear aromatic compounds, sulphonated dyes or sulphonated polymers the preferred deflocculant, which should be different from the crystalgrowth inhibitor, may include water-soluble polysaccharide derivatives, polyacrylic acid, polyvinyl pyrrolidone, sodium lignosulphonate and/or a salt of a condensate of naphthalene sulphonic acid with formaldehyde.

Title: Method of and system for power line carrier communications
Inventor: LAPORTE ERIC
IPC: H04B1/713
Filed: 1990-04-25
Granted: 2000-10-17
Abstract: The transmitter in a power line communications system applies to the power line encoded logical-one and  logical-zero  bit  signals  consisting  of  signals formed  respectively  of  predetermined  different sequences of frequencies.  The receiver, coupled to the power line,  includes a first homodyne,  non-coherent, quadratic demodulator for demodulating the logical-one bits  and a  second for demodulating  the logical-zero bits.  The first demodulator produces, locally, and in first  and  second  channels,  respectively,  a  first reference signal that is a replica of the logical-one bit  sequence  of  frequencies  and  a  second reference signal that is the replica in quadrature.  The second demodulator produces, locally, and in third and fourth channels, respectively, corresponding third and fourth reference signals for the logical-zero bit sequence. Each of  the four reference signals  is applied to a corresponding analog multiplier for multiplication by the input signal in each channel.  The output of each multiplier is applied to a low pass filter that passes only the dc component of the product signal which in turn is squared.  The resultant signals in the first and second channels are summed to provide a first output signal, and the resultant signals in the third and  fourth  channels  are  summed to provide a second output signal.   Compensation circuitry cancels error voltages developed in the demodulation channels as a result of component offset, and the two output signals are integrated over a bit period and then compared to each other to detect a logical-one or logical-zero bit.

Abstract: This is an improved process for producing an optically active atenolol useful as a .beta.-adrenergic blocker for the treatment of angina pectoris, arrhythmia and hypertension.          In this process a phenol compound is reacted with an optically active epihalohydrin to give an intermediate, optically active glycidyl ether compound.  The intermediate is then reacted with isopropylamine.  Purification of the optically active atenolol in high yield is achieved by forming a salt of atenolol with a Br~nsted's acid.  The salt of optically active atenolol having high optical purity can be separated from the salt of racemic atenolol by a solid-liquid separation method.

Abstract: COAST-SYNC-COAST DOWNSHIFT CONTROL METHOD FOR CLUTCH-TO-CLUTCH TRANSMISSION SHIFTING            Abstract of the Disclosure A coast-sync-coast control method for clutch-to-clutch shifting in which an engine control is employed to synchronize the engine speed with the transmission input speed at a point where the input speed would otherwise exceed the engine speed.  The shift is referred to as a coast-sync-coast shift since (1) it is initiated at a coast condition where the input speed is higher than the engine speed, (2) it is completed at a synchronous condition where the speed differential across the on-coming clutch is at or near zero, and (3) a coast condition recurs immediately after the shift.

Abstract: A fabric light control window covering in which fabric vanes are adhesively bonded between two sheer fabric sheets such that relative movement between the sheer fabric sheets  in a direction perpendicular to the longitudinal direction of the fabric vanes changes the angle of the fabric vanes and, thus, controls the amount of light admitted through the shade.  The vanes are bonded to the sheer fabric sheets in a manner which tends to bias the sheer fabric sheets together to the nonlight admitting position.          Also, disclosed are methods and apparatus for manufacturing the above window covering.  The method features linear application of adhesive  to  the vane material  which provides  for  a  uniform appearance in the finished product.  A heat setting process and apparatus is disclosed in which the bonded layers of sheer fabrics and vanes are fed between belts over hot and cool surfaces, under uniform tension and pressure. This provides for heat setting of the layers of the window covering to a uniform temperature-size relationship without inducing wrinkles or distortion into the fabric during heat setting.

Granted: 2002-12-10
Abstract: The present invention relates to translucent and thermodynamically stable diesel fuel compositions having improved combustion efficiency and reduced smoke, particulate, CO, and NO x emissions. The diesel fuel compositions comprise a diesel fuel, water, or an aqueous solution of a low molecular weight alcohol and/or a water-soluble reagent, and a surfactant system which comprises a balanced blend of one or more hydrophilic surfactants and one or more lipophilic surfactants, wherein the diesel fuel composition can contain as high as 30 weight percent of aqueous phase with an aqueous phase/surfactant ratio at least 2/1.      The surfactant system may contain, in addition to the hydrophilic and lipophilic surfactants, cosurfactants and polar organic solvents. The reagent solution comprises aqueous solutions of an additive selected from the group consisting of inorganic oxidizing agents, low molecular weight polar organic oxidizing agents, and nitrogen oxide-containing compounds which act as cetane improvers and/or combustion modifiers.      These additives offset the well-known loss in cetane number and/or the ignition delay caused by dispersed or microemulsified water and eliminate the need to change engine operating parameters.
